BTA opening Only at night

[maroun.c]

A friends pink BTA isnknly opening at night. It's a big size fluorescent pink BTA that came in on a wild shipment. Looked great in I production tank and kept amazing fluorescent pink bubbles. Inside was a bit whitish on arrival but showed a hint of blue after. It lost the bubbles to streaming ling tentacles over few mo this and looks as I. Below video taken befor lights out with no lights on in the room. It soon closes after lights on and has lost some volume since it came. He feeds 1/4 shrimp twice a week and it feeds fine..
It's under AI lighting at around 40 percent max.
Any idea why its closing at daytime and opening all night and if he needs to do anything for it ?

In Introduction tank where it stayed for around couple months

Abd pic from today under lights off. It will close down as soon as lights go on

Thanks for any info as it had us baffled.over last weeks on why it's not opening at daytime and opening up at night time.

Was it a deep water specimen?

Vendor claims these come from 1 meter depth but I'm not sure if this is accurate.

The only thing that makes sense is lighting is bothering it.

Yeah but at that light intensity I doubt it's getting more than 100-150 par at best. It's also not moving. I have never seen an anemone open at night.

I'd stop feeding it IMO.

I have many that close at night and many that stay wide open...sometimes one nem does both on diff nights. But all open during the day...just for kicks try placing egg crate or similiar over his side to reduce the light and see what he does...

Any update my bta is doing this too.

Still hanging on . Not doing great unfortunately, it kept opening more at night and loosing volume. The tank he had it in had Dino’s since last month as well and it bubbles were mostly deflated and mouth gaping. He brought it over and it’s now in my coral quarantine to see if it’ll do any better.

My doesn't look so good either. Fingers crossed.
